[PATCH] ppc64: Quieten lparcfg

If we dont have permission to read some information from the hypervisor,
lparcfg outputs a warning on the console. Now that lparcfg is world
readable this is a problem.

Dont warn in the case of H_Authority, remove some unnecessary function
prototypes and fix whitespace damage in a structure as well.
